panic at _bus_dmamap_sync

[6bone%6bone.informatik.uni-leipzig.de@localhost]

hello,

I am testing NetBSD 4.99.72. (amd64) During the boot the kernel crashed. 
You can find the screenshot at http://suse.uni-leipzig.de/dump6.jpg

You can also download the kernel, map and gdb file

http://suse.uni-leipzig.de/netbsd.kernel
http://suse.uni-leipzig.de/netbsd.map
http://suse.uni-leipzig.de/netbsd.gdb

Any idea what the problem can be?
It looks like a network error, but I am not sure.


Thank you for your efforts
Uwe
